Elderly pets are more
susceptible to stress-induced infection than younger ones. This condition is
known as immune senescence.

This condition is
well-known in humans, but all mammals that survive well into their
biological lifespan are also vulnerable. Human medicine attributes this to
changes in the traditional immune system (immunoglobulins). However, because
stress is often the trigger, we need to examine the gut microflora. These
beneficial microorganisms are the frontline of the immune system.

Although these microbes
are giants in their own world, they are very susceptible to changes in the
animal and the flow of nutrients. This flow can change or stop in older pets
because of:

Poor condition of
the teeth and/or gums
dental health is important for the acquisition and mastication of
food. If the teeth and/or gums are sore or worn down, they could limit
nutrient intake.

Access to food
is the oldster having trouble getting around? Has arthritis made the
simple act of going to the food dish too painful? Make sure both food
and water are easily accessible at all times. This may mean sequestering
the pet in a small room to minimize movement during meals.

Nutrient intake is
also hampered by decreased digestion in older animals. Make sure their
food is appropriate and easily digested. Many older pets are less active
and therefore require lower daily energy intake. Obesity can exacerbate
arthritis and also weaken the immune system further.

Stressful events
assume that any change in the normal routine is a potential source of
stress. Everyday stresses are compounded by painful movement. Stresses
to be especially aware of include vet visits, and time left alone.

Prevention is the key

The immune system can be
strengthened and the beneficial microorganisms allowed to repopulate by
feeding a daily probiotic such as MSE Natural Defense. For major stresses,
the preventive use of more concentrated forms such as MSE Paste and Liquid
Rescue may abort or downgrade potentially fatal infections if used
immediately after a major stress, preferably for several days. This is
recommended because the beneficial microorganisms take at least two weeks to
regain their dominance after a major stress. Smaller amounts of either Paste
or Liquid Rescue can be fed on a daily basis (1 to 2 cc) for most dogs.
Elderly cats usually prefer MSE Natural Defense Soluble (see below) mixed
into their food.

The good news is that
immune senescence is not inevitable, and there is evidence that it can be
reversed. The regular use of probiotics can help extend a pet s life, and
also help improve the quality of those golden years.
